Abstract

The influence of flow on the fiber orientation in injection molding of short-fiber composites leads to both anisotropy and inhomogeneity of the mechanical response. An anisotropic elasto-viscoplastic constitutive model is developed to capture the anisotropic and time-dependent behavior and plasticity controlled failure of short-fiber composites. This model will be numerically implemented in a 3D framework and will be evaluated through simulation of the demonstrator problems.
